Synergistic Research Luminescence Phase II

All I use/recommend is S.R. Only - for the $ they are the best out there ( I've tried quite a few cables )!
I use S.R. Reference X-Series XLR (Balanced)in my Whole System : very Detailed, Open/Transparent, very Analog sounding, and Huge sound stage, real Neutral and Quiet Cable. I'll put this cable ( X-Series - Active Shielding ) against cables Much More Expensive - this Cable blows them away! Go S.R. Reference all the Way, Ive tried the Tara Labs Decade and AQ Diamond X3 - didn't like them ( closed/restricted sounding - Not as much Detail ), S.R. Reference much much Better sounding.

Good luck and Enjoy!

the only way to compare these cables is in your own rig. Any other rig synergises differently; the reactance charactaristics of your equipment & how they interact with the cabling is different for each & every rig out there, so the sonic signature is never the same for any two systems. The Resolution Reference MKII is a nice cable at my house, but I liked the Designer Reference-X even better.
My Synergistic dealer likes the Looking Glass & Kaleidoscope cables too, but he rants about the Luminesence as being strictly a band-aid cable for problem rigs. I don't know about that, but I do know that the Looking Glass worked a bit better for me than the Kaleidoscope. The Resolution Reference was of course better than Looking Glass in some respects; I do recall noticing improved bass authority with the Res Ref. I'm sure there were some other differences, but anymore I don't recall what they were.
If you'd like to compare the makeup of my rig to your own, just click on my username & scroll down the bio until you see the system components list.
This is the best that I can answer your question.

My equipments are all Sony ES:

Sony CDP-XA7ES connects to TA-E90ES (preamp) by Synergistic Research Luminescence Phase II RCA. Then TA-E90ES connects to TA-N90ES (amp) by Tara Labs Decade XLR.
My speaker is Paradigm Reference Studio 60 with Tara Labs Prime 1000 as speaker cable. I uses Synergistic Research Master AC power cord for my entire system. The sound quality overall is very good already with define bass and extended high but the mid could be a little bit more open. I plan to buy Audioquest Diamond X3 or Diamond Extreme XLR to replace my Luminescence Phase II. Do I get significant better in sound quality? Has anyone done the comparation between the AQ Diamond X3 and AQ Diamond Extreem? Thank you for your information.

I'd experiment a bit with some other AC cords first. If you prefer the Synergistic line, they offer 4 other cords above the Master Coupler level.

I am using a pair of Wasatch 105-U interconnects between my Threshold pre and a TA-N90ES and find the results most satisfying. I was using SR Alpha Sterling and then Cardas Hexlink, but found a quite astounding improvement with the Wasatch. So much so that I have purchased Wasatch interconnects for the balance of my system and have ask them to build me a 105 level phono interconnect. I have to admit that I didn't think cables made that much difference once one spent about $400, or so. But Wasatch changed my mind. You should see if you can audition a pair. I definitely did not believe it until David Lewis proved it to me. Will most likely spring for their speaker cables, as well, at some point.
